Landslide Remediation – Buderim Tramway Trail

The Goal

The primary goal of this project was to safely remove uncontrolled fill and re-establish a stabilised embankment and retaining wall. This remediation work was essential to protect and preserve the heritage-listed Buderim Historic Tramway Trail following a landslide event.

The Challenge

A major challenge of this project was navigating the highly constrained site access, which was restricted entirely to a private residential driveway on Mons Road. Our team had to carefully manage heavy machinery and material deliveries on steep, unstable terrain while minimising disruption to adjacent residents. Furthermore, we needed to ensure the strict protection of the surrounding local flora, fauna, and heritage assets.

The Solution

To resolve the access and stability issues, we executed a carefully staged construction sequence. We mobilised specialised equipment to drill and install deep concrete bored piers, socketing them securely into the foundational sandstone rock. From there, we constructed a robust, multi-tiered sandstone block retaining wall , paired with controlled backfilling and compaction to safely rebuild the embankment.

The Result

The Buderim community now benefits from a fully stabilised and safe environment. We successfully reconstructed the embankment, upgraded the stormwater drainage system to divert water away from the site , and reconditioned the gravel trail. With final environmental stabilisation completed—including the installation of jute matting and revegetation—the heritage trail is preserved and protected against future weather events.
